Miniature rose plant named `Meigloyel`

ABSTRACT

A new and distinct variety of rose plant of the miniature class is provided which abundantly forms attractive double Chinese Yellow blossoms which are stable and will retain their coloration upon the passage of time. The plant is bushy and dense with considerable branching. The blossoms possess a light fragrance. The plant is well adapted to pot forcing under greenhouse growing conditions, and grows well on its own roots. Also, the plant can be grown as attractive ornamentation in the landscape.

SUMMARY OF THE INVENTION

The new variety of miniature rose plant was created by artificial pollination wherein two parents were crossed which previously had been studied in the hope that they would contribute the desired characteristics. The female parent (i.e., the seed parent) of the new variety was the product of the pollination of the Meigronuri variety (U.S. Plant Pat. No. 4,625) and the Yellow Pages variety (non-patented in the United States). The male parent (i.e., the pollen parent) of the new variety was the product of the pollination of the Schobitet variety (U.S. Plant Pat. No. 5,690) and the Lavglo variety (U.S. Plant Pat. No. 7,136). The parentage of the new variety can be summarized as follows:

    (MEIGRONURI×YELLOW PAGES)×(SCHOBITET×LAVGLO).

The seeds resulting from the above pollination were sown and 18 small plants were obtained which were physically and biologically different from each other. Selective study resulted in the identification of a single plant of the new variety.

It was found that the new variety of miniature rose plant of the present invention possesses the following combination of characteristics:

(a) forms in abundance attractive double blossoms which stably exhibit Chinese Yellow coloration under greenhouse growing conditions,

(b) exhibits a bushy growth habit with considerable branching, and

(c) possesses a good ability to undergo pot forcing under greenhouse growing conditions.

The new variety well meets the needs of the horticultural industry. It is particularly well-suited for use as attractive ornamentation in the landscape or for growing as a decorative pot plant.

The new variety has been found to undergo asexual propagation in France by a number of routes, including budding, grafting, and cuttage. Asexual propagation by the above-mentioned methods as performed in France has shown that the characteristics of the new variety are strictly transmissible from one generation to another.

The new variety has been named the Meigloyel variety.

BRIED DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant parts of the new variety. The rose plants of the new variety were two years of age and were observed during July while growing on their own roots outdoors at LeCannet des Maures, Var, France.
